Description

The A/T89C51AC2 is a high performance Flash version of the 80C51 single chip 8-bit

microcontrollers. It contains a 32 KB Flash memory block for program and data.

The 32 KB Flash memory can be programmed either in parallel mode or in serial

mode with the ISP capability or with software. The programming voltage is internally

generated from the standard VCC pin.

The A/T89C51AC2 retains all features of the 80C51 with 256 bytes of internal RAM, a

7-source 4-level interrupt controller and three timer/counters. In addition, the

A/T89C51AC2 has a 10-bit A/D converter, a 2 KB Boot Flash memory, 2 KB EEPROM

for data, a Programmable Counter Array, an XRAM of 1024 bytes, a Hardware Watch-

Dog Timer, and a more versatile serial channel that facilitates multiprocessor

communication (EUART). The fully static design of the A/T89C51AC2 reduces system

power consumption by bringing the clock frequency down to any value, even DC,

without loss of data.

The A/T89C51AC2 has two software-selectable modes of reduced activity and an 8-

bit clock prescaler for further reduction in power consumption. In the idle mode the

CPU is frozen while the peripherals and the interrupt system are still operating. In the

Power-down mode the RAM is saved and all other functions are inoperative.

The added features of the A/T89C51AC2 make it more powerful for applications that

need A/D conversion, pulse width modulation, high speed I/O and counting capabili-

ties such as industrial control, consumer goods, alarms, motor control, among others.

While remaining fully compatible with the 80C52, the T8C51AC2 offers a superset of

this standard microcontroller. In X2 mode, a maximum external clock rate of 20 MHz

reaches a 300 ns cycle time.
